2.5 Gbps Single Mode SFF LC Transceiver
C-1XX-2500(C)-FDFB-SLCX
Recommended Circuit Schematic
Inputs to the C-1XX-2500(C)-FDFB-SLCX series transmitters are AC coupled and internally terminated through 50 ohms to AC ground.
These transceivers can operate with LVPECL or CML logic levels. The input signal must have at least a 200 mV peak to (single ended) signal
swing. Output from the receiver section of the module is also AC coupled and is expected to drive into 50 ohm load. Different termination
strategies may be required depending on the particular Serializer / Deserializer chip set used.
The C-1XX-2500(C)-FDFB-SLCX series product family are designed with AC coupled data inputs and outputs to provide the following
advantages:
■
Close positioning of SERDES with respect to transceiver; allows for shorter line lengths and at gigabit speeds reduces EMI.
■
Minimum number of external components.
■
Internal termination reduces the potential for unterminated stubs which would otherwise increase jitter and reduce transmission
margin.
Figure 1 & Figure 2 illustrates the recommended transmit and receive data line trminations for SERDES with CML and LVPECL Inputs / Outputs
respectively.

Signal Detect
The C-1XX-2500(C)-FDFB-SLCX transceivers are equipped with LVTTL / LVPECL signal detect outputs. The standard LVTTL output eliminates
the need for a LVPECL to LVTTL level shifter in most in most applications.
